The recently revealed making-of clip offers fans a detailed look at the filming locations, sets, costumes, camerawork, and the members — of course — who just can’t seem to stop goofing around, especially when the main cameras are no longer rolling.

Chilling on top of a fancy ride, Bobby and Chanwoo introduce the set and how it relates to their music video concept, saying, “This is where the 21st century rebels gather to bop their heads to the beat.”

The must-see highlights include B.I and Bobby’s short yet intense arm toning sesh, Jinhwan and Chanwoo’s random goofing session, and Junhoe and Yunhyeong‘s battle of who can make the most hilarious facial expressions. Not to forget the ever-so-adorable Donghyuk, who simply lights up the set with his infectious smile.
